I encountered the same issue yesterday. And it's blocking me a lot right now. What should we do? @manfredsteyer

[OldShaterhan]

At this point I'm basically having a copy of that in separate directory and I'm copying in to node_modules, but any npm install basically removes it from there.

[nlegncn]

I added as optionalDependencies like:

npm install @oxc-parser/binding-win32-x64-msvc --save-optional

but still I can not build my project with angular 21 update because of other issues. But you can use maybe with temp solution

This one nuxt/nuxt#33480 looks a bit similar?

Same problem here - have to install it manually on every windows dev environment but cannot add it to the main package.json since this would obv. break linux builds

[OldShaterhan]

@lmoesch I may be wrong, but this package probably has OS set, so it probably would install only on Windows if it would be in optionalDependencies in package.json, that's what my Copilot & Gemini suggested, but I haven't tested it yet.

Nevertheless, it should be covered on the lower level than our apps.
